Good morning, I am writing in a matter that has been bothering me for several months with talk here about a month. I am a 24-year-old person who from the beginning of his month had an irregular cycle from 28 to 35 days always 5 days, while three days lasted always normally, the fourth stopped and the fifth were a bit more modest. For 2 years I have been doing cytology and ultrasound at the gynecologist, which has always been unchanged, correct without deviations. The last one I did was in May. Everything in order unchanged. The only thing that the gynecologist on the ultrasound said that the ovaries are healthy and everything else is in order but through the muscle which, as it turned out, I have after my mother located on the left side at the top of the vagina may have slight problems with getting pregnant. But that's just a guess because my mom went normally and has two children. And I have nothing to worry about. But returning in January, the month came normally and ended in February, but in March due to sudden and severe stress lasting up to 2 weeks of the month after 40 days, the next from April to July appeared normally every 28-32 days, i.e. in the norm as it was always. The situation changes in August because the month comes after 38 days I felt that it could have been the reason for the flu that I went with high fever over 39 °. At the end of August, unfortunately, I had two days of work-related situation again and stress appeared. The situation repeats itself passes 36 days and the period as it was not so is not, I will add that exactly 2 weeks after a month in August I had days of ovulation which always look the same for several years ovarian pain, transparent gestures of mucus in the structure "glutaty" but this race without a visible graz color which once created my anxiety but the gynecologist said that this hemating during ovulation when the cell is released can be on time and does not have to. My main question is whether it is normal that menstruation can appear every 38 days? And can it be normal? I know that the range for menstruation is normal between 28-35 days or maybe it may not be true and for my body it can be normal or temporary? I will add that I exclude pregnancy because the tests came out negative.
